// FAQ
Everything you need to know
What purity are your peptides?
Delta peptides are verified at ≥99% purity via reverse-phase HPLC analysis. Each lot undergoes additional mass spectrometry confirmation by independent third-party laboratories.
Do you include a Certificate of Analysis (COA)?
Yes. Tested products come with a Certificate of Analysis (COA) from an independent third-party lab. This document verifies purity, identity, and quality, and is accessible for full transparency.
How should I store my peptides?
For optimal stability, peptides should be stored in a cool, dry environment. Lyophilized (powder) peptides are best kept refrigerated (2–8°C), while reconstituted peptides should be stored in a refrigerator and used within a short time frame. Avoid repeated freeze-thaw cycles.
How fast do you ship?
Orders are typically processed within 24–48 hours. Shipping times vary based on location, but most domestic orders arrive within 2–5 business days. Tracking information is provided as soon as your order ships.
What is backordering?
Backordering means that when you purchase a product that is temporarily out of stock, we still accept your order and reserve it for you.
Because your product is being specially restocked, backordered items typically have a slightly longer delivery time (usually 1–2 additional weeks).
In return, we offer free shipping on your entire order when a backordered product is included, as a way to offset the extra wait.
What is your return and refund policy?
Due to the sensitive nature of our products, we do not accept returns. However, if your order arrives damaged or there is a verified issue, reach out to our customer support to recieve a potential full refund or replacement order. Customer satisfaction and product integrity are our priorities.
How can I contact support?
You can reach our support team via email or contact form on our website. We aim to respond to all inquiries within 24 hours. Whether you have questions about products or orders, we’re here to help.
